Acid Free A4 Paper
For notes, printed or handwritten, family tree charts, print outs etc.
Bright white A4 90gsm or 100gsm, high quality archival acid free paper.
It is manufactured to ISO 9706. This means it must conform to a particular set of standards such as pH level, alkaline reserve (calcium carbonate equivalent), tear resistance and resistance to oxidation. It is the alkaline reserve that helps the paper resist contamination from external sources over the years.
For the family historian, archival acid free paper is essential for the safe long term preservation and storage of research notes and documents.
NB. If you buy inkjet printer ink with a branded name rather than compatibles, these are usually acid free, but check with the supplier or manufacturer of your ink cartridges.
